The Agreement

Under the terms of the deal, Eos and CAPAC Energy — a German developer and operator of battery energy storage systems — have established an exclusive partnership across Germany, Austria, and Switzerland through 2031. The agreement includes a 750 MWh capacity commitment with a pathway to scale up to 2 GWh of Eos’s Indensity zinc-based long-duration energy storage deployments. CAPAC Energy has been designated as Eos’s exclusive distribution partner in the region. As purchase orders are issued under the agreement, they will be included in Eos’s reported backlog.

Critically, CAPAC Energy is already moving. Construction on its first Eos projects in Germany has begun, with commercial operations targeted for late 2026.

Why Germany?

Germany is rapidly emerging as a critical market for long-duration energy storage. The ongoing phase-out of coal-fired generation, ambitious renewable energy targets, and increasing grid complexity are driving demand for flexible, multi-hour storage solutions. Recent regulatory developments—including updated building code privileges for grid-scale batteries and a capacity market mechanism expected to launch in 2027—are further enhancing the long-term outlook for storage deployment in the market.

The Bigger Picture

The DACH agreement marks Eos’s first international commercial framework for Indensity, positioning the company for broader European expansion. The partnership also creates an opportunity to evaluate local manufacturing and assembly capabilities in the European Union, which could strengthen supply chain security and support skilled industrial employment in Germany and neighboring markets.

“This partnership represents more than a supply agreement — it establishes Eos’ entry into a critical international market with a customer already moving projects into construction,” said Nathan Kroeker, Chief Commercial Officer of Eos.
